Equipment Manual, 10/2023, C79000-G8976-1403-17
Install a circuit breaker rated no higher than 20 A between the device and the
supply mains.
Whenever possible, use a separate circuit breaker for each power supply.
For maximum redundancy in a dual power supply configuration, use two
independent power sources.
A socket outlet/disconnect device must be installed near the device and be easily
accessible.
Equipment must be installed according to applicable local wiring codes and
standards.
Remove the safety cover.
If equipped, remove the power terminal block plug from the device.
NOTICE
European-style (Euroblock) terminal block connections
When connecting wires to a European-Style (Euroblock) terminal block plug,
note the following requirements:
• When stripping wires from the external power source, strip up to 6.6 mm
(0.27 in) ± 0.5 mm (0.02 in) of insulation.
Do not strip more than 7.4 mm (0.29 in). Stripping more than the
recommended amount can leave non-insulated wire exposed outside the
terminal block plug.
6.6 mm (0.27 in) ± 0.5 mm (0.02 in)

• Terminate wire ends using insulated wire ferrules, when possible.
• When inserting a wire into the terminal block plug, make sure the wire lead
is not visible. Only the wire insulation should extend from the terminal
block.
• Using a slotted screwdriver, secure wires to the terminal block plug by
torquing the captive screw (above the installed wire lead) to 0.5 N·m (4.5
lbf-in).
